JOHN BARTON, OF GLASGOXV, COUNTY OF LANARK, SCOTLAND.

ANCHOR.

SPECIFICATION forming part of Letters Patent No. 341,872, dated Mlay 18,1886.

Application filed November 4, 1885. Serial No. 181,846. (No model)Patented in England December 7,1883, No. 5,663.

To all whom it may concern.-

Be it known that 1, JOHN BARTON, a subject of the Queen of GreatBritain, residing at Glasgow, in the county of Lanark, Scotland,engineer, have invented certain new and useful Improvements in Anchors,(for which I have received Letters Patent in Great Britain N 0. 5,663,dated December 7, 1883,) of which the followingis aspecification.'

My said invention relates to anchors of the kind having movablefluke-pieces; and its ob ject is to improve the construction and increase the efiiciency of such anchors, while, in some modifications,dispensing with pins, keys, or cotter-sin any position where they wouldbe subjected to strain or be liable to have their action interfered withby the 10L g ment of sand or earth. At the same time a portion of myimprovements may in some cases be combined with arrangements comprisingpins, keys, or cotters, and in such cases the defects of sucharrangements will be considerably reduced.

Examples of anchors made with my improvements are delineated on twoaccompanying sheets of explanatory drawings, and are hereinafterparticularly described.

One modification of my improved anchor is shown on Sheet 1 of thedrawings, Figures 1 and 2 being edge and side views of the completeanchor; Figs. 3 and 4, similar views of the shank by itself; Figs. 5 and6, aside view and a section of part of the fiuke-piece; Figs. 7 and 8,sections of different parts of the fluke; Fig. 9, a plan of a box whichworks on the shank-head, and Fig. 10 is an inside view of one-half ofthis box; Figs. 11 to 20 on Sheet 2 of the drawings are similar viewsexplanatory of a second modification.

In these drawings thesame referencenumerals are used to mark the same orlike parts wherever they are repeated.

In the anchor shown on Sheet 1 of the drawings the middle 21 of thefluke-piece 22 21 22 fits and can turn in a round eye, 23, formed in thehead 24 of the shank 25, and its movement to either side is limited by aprojecting segment, 26, formed 011 it and working in a recess, 27,formed in one side of the shankhead 24. The fluke'piece when in itsfinished shape can be entered into its place through the eye 23 in theshank-head 24, and after beout of place.

ing so entered a pair of plates, 28, are applied, being strung one uponeach arm of the duke piece, and brought close to the opposite sides ofthe shank-head 24, and, after being bolted together, prevent thefluke-piece from getting The plates 28 when bolted together form a kindof box external to the shankhead 24, but which moves with thefluke-piece 22 21 22, and is made with angular inner corners, 29, ofwhich. the one happening to be under-most catches in the ground, so asto make the fiukes 22 turn downward and bite or take hold as quickly aspossible. \Vith this arrangement and configuration the anchor will takehold much more quickly and certainly than many anchors having movablefluke-pieces. The other corners. 30, of the box-plates 28 are rounded,so that the cable is not liable to ion] on them. The dukes 22 are madeto project from the fluke-arms on the inner side only. They are convexon their faces, as is shown by the Figs. 7 and 8, and their edges areplanes at right angles to the plane of their center lines. Thefluke-piece of this improved shape is not only easier to make, but isalso better adapted to resist the strains to which it has to besubjected. The bolt heads and nuts of the box-plates 28 are sunk intothe plates, so as to present no projections which would be liable toinjury. The steadying arm-piece 31 is made with a bored eye, and isfitted on a turned bearingsurface on the shank 25, being secured by apin passing through it and the shank.

In the modification shown in Figs. 11 to 20, on Sheet 2 of the drawings,there is substituted for the projecting segment 26 on the middle of thefluke-piece and the recess 27 for the projection 26 to work in anelongated recess, 32, formed in the middle part, 21, of the fluke-piece,and a steel pin, 33, fixed in the shank-head 24 and projecting into therecess 32. The recess 32 extends sufliciently round the middle part, 21,of the fluke-piece to allow of this piece assuming the proper angle ofabout forty-one degrees of the circle to either side of the shank. Thesteel pin 33 is entered inward through a hole bored for it in theshank-head 24, and is fixed by a cross-pin, 34, which may also serve forthe attachment of a shackle, 35, for a buoyrope. In some cases theprojecting'pin and elongated recess 32 33 may be used, in combinationwith the analogous parts, 26 27, Sheet 1, the shank-head 24: being madethick enough for both, or the device 26 27 being applied at the innerside of the fluke-piece or opposite to the device 32 33.

Having thus particularly described my said invention and the manner ofperforming the same, I have to state that I do not restrict myself tothe precise details herein described or delineated; but that \Vhat Ibelieve to be novel and original, and claim as the invention secured tome by and in terms of the hereinb'e'fore-in-part recited Letters Patent,is

1. An anchor in which the fluke-piece is inserted through an eye in theshank-head, is retained by a box-piece, and is controlled in its angularmovement by a projection and elongated recess in the joint parts of theflukepiece and shank-head, substantially as set forth.

JOHN BARTON.
